Claims.

This invention relates to new and useful improvements in means for the protection of the civilian population against aerial bombing, poison gases and bacteriological warfare, and it has for 5 its object especially to protect such vulnerable spots, or places, upon which aerial bombing would naturally center, and where at any rate the relatively greatest damage might be done.

While some of the improvements, as herein 19 described and disclosed, might very Well be use-d independently of each other, it will be obvious that a combination of the said improvements will in a most desirable manner fully solve this important and vital problem.

It is also evident that the means for the purposes herein stated may be installed in any suitable building in a comparatively short period of time.

As the construction of the said improvements is rather simple, the cost of the installation should be proportionately small, and not form a prohibitive obstacle.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts,

' hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this specification, and in Which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 shows in a side elevation part of our devised means.

Figure 2 shows a correlated arrangement, illustrating projecting tubes at the top of a building Figure 3 is a view similar to Figure 2, and showing varied embodiments of the safety-system.

While various modications may be made, and sizes and measurements decided, according to the respective surroundings, the illustrations herein are made, and thought, to clearly set forth the principles of our safety-system.

Referring more particularly to the drawings, in Figure 1 has been shown an adequately airtight room, the entrance to which is protected by double doors, one oi which has been shown at It; the said -doors should be arranged in such a manner, that one is always closed, when the other is open. The Windows should be protected by inside strong shutters.

In the said room are arranged two electrically operated blower-fans; one H for the intake of fresh air, and the-other l2 for the exhaust; the said fans and the mechanical construction of the latter` being of the well known kind. A tube, preferably of metal, and conveniently mounted in the elevator-shaft, is indicated by i3, and has for its purpose to convey a fresh supply of air, which is distributed to the number of rooms desired by means of the blower-fan l l, and the distributing tube ill the air is conveyed from the pipe or tube 5, i3 through the wall t5 of the room by means of a short pipe iii; the latter pipe connects with a hose I l, which conveys the air through a tank i8, containing chemical neutralizing means; and from the said tank the air is nally by means of 10v another hose 2l brought into contact with the blower-fan H for the purpose ot distribution.

The said tank and fans may be mounted on a suitable table or stand l, as shown.

An exhaust tube 2G, similar to the tube i3, but 15s of a slightly smaller diameter, is also shown in Figure 1.

The exhaust is drawn by the fan ii! from different rooms by means of a tube 2 l, and is by means of the hose 22, which connects with a short pipe 23 20 extending through the wall i5, carried out into the exhaust tube 20. An electric wire for connecting the apparatus with a source is shown at 241.

The short pipes it and 23 are provide-d with 25 valves, or closing means, as indicated at 25 and 2t, in order to prevent an iniiow oi foul or polluted air, if the hoses of the apparatus are disconnected.

The dual system, thus shown, may be conveniently installed in large as well as smaller 30 buildings.

In skyscrapers elevator-shafts may be used, one for each purpose, respectively, as described; air-pipes are in this case mounted in the upper parts of the said shafts, while hoses are con- 35 nected to the lower parts of these, respectively.

In Figure 2 has been shown the relative arrangement of the outside communication, or communicating means of this system. Thus 28 indicates a buffer-tube for the protection of the elongated and outside extending portions of the fresh-air inlet and exhaust tubes I3v and 2t', respectively. This buffer-tube has in turn its lower end near-est the roof supported by a trestleframework 22S in order to give it more stability, 45 and resistance against the eifect of any damage and shock, by means of vibration, to which it may be exposed through exploding bombs; in like manner said buffer-tube will in turn lend protection to the fresh-air inlet and exhaust tubes, for a 50w considerable distance of the length these tubes project above the roof of a building.

The buffer-tube itself may have the spaces around the pipes i3 and 2B filled with suitable protecting material, such as sand, or steel shav- 55 ings, while a cap 3D, formed with the appropriate openings therein, closes the tube.

The air pipe I3 extends a. considerable distance above the buffer-tube, as shown, and has its mouth closed by a hood-member 3l formed with appropriate side-openings 32 therein for the inlet of fresh air. The exhaust pipe 28' extends a little distance above the fresh air pipe and has its end portion terminated into several divergent radially extending tubes 33, open at their ends and serving the purpose of letting out the eX- haust.

At the center of the cap 30 suitable arrangements are made for the erection of radio receiving means shown at 34.

In Figure 3 has been elaborately shown the Varied embodiments to which this safety-system may be susceptible. Thus in case of a church, the tower 35 may take the place of the buifertube 28.

It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope oi the appended claims, without departing from the spirit of the invention, and we do not therefore wish to limit oiu'selves to the construction and arrangement shown and described herein.

What we claim as new, and desire to secure by Letters Patent o the United States, is:
